Mesoplodon

Common Names

The common names for Mesoplodon species vary depending on the species. Some common names include:

• Sowerby's beaked whale (Mesoplodon bidens)
• Gervais's beaked whale (Mesoplodon europaeus)
• True's beaked whale (Mesoplodon mirus)
• Blainville's beaked whale (Mesoplodon densirostris)

Characteristics

Mesoplodon species share several common characteristics, including:

• Elongated, pointed beak: This is the most defining feature of beaked whales. The beak is used to catch and hold prey, which includes squid and fish.
• Small size: Mesoplodon species are relatively small for whales, with most species reaching a length of 4-6 meters (13-20 feet).
• Dark coloration: Most Mesoplodon species are dark gray or black in color, with some species having lighter patches on their bellies or flanks.
• Single dorsal fin: Mesoplodon species have a single, prominent dorsal fin that is located about halfway down their back.
• Two pairs of teeth: Most Mesoplodon species have two pairs of teeth that are located in the lower jaw. These teeth are typically small and pointed, and they are used for catching prey.

Environments

Mesoplodon species are found in all the world's oceans, but they prefer deep waters, typically at depths of 1,000 meters (3,300 feet) or more. They are often found in areas with strong currents, which may help them to locate prey. Mesoplodon species are highly social animals and are often found in groups of 2-10 individuals.
